Short summary
The widespread availability of low-cost electronics has created new opportunities for affordable geophysical equipment. Electromagnetic geophysical methods allow users to examine the electrical properties of the ground. The Colorado School of Mines electromagnetic system (CSM-EM) is a proof of concept instrument capable of sensing shallow conductive objects and costs under USD 400 to build. We tested the system in a laboratory setting and validated it over a metal target outdoors.
